A vertical powder cooler

Abstract

A vertical powder cooler, comprising a shell, the top of the shell has a feed port, the bottom has a discharge port, and also includes a feeding grate, a feeder and a feeder, the feeding grate and The feeder is set perpendicular to the falling direction of the material, the edge of the feeder is fixed on the inner wall of the housing, the feeding grate is set close to the feeding port, the feeder is above the feeding grate, and after it communicates with the driving device Rotating, also includes air supply device for good cooling effect. The invention realizes the vertical transportation of the material while cooling the powder material, and has the advantages of simple structure, low energy consumption, good cooling effect and the like.

Description

technical field [0001] The invention relates to a cooler, in particular to a vertical cooler suitable for powder. Background technique [0002] Reducing the temperature of high-temperature materials is a very necessary process in many fields. For example, in the process of gypsum production, the calcined plaster powder can reach about 150°C. If it enters the homogenization bin through related equipment without sufficient cooling, the accumulated heat may be too high in the bin. The powder will be calcined again, which will affect the clinker coagulation time and crystal water content and other indicators. In addition, in the process of conveying high-temperature clinker, excessive temperature will also have an adverse effect on related equipment.

Problems solved by technology

For example, in the gypsum production process, the calcined plaster powder can reach about 150°C. If it enters the homogenization bin through related equipment without sufficient cooling, the accumulated heat may be too high in the bin. The powder will be calcined again, which will affect the clinker coagulation time and crystal water content and other indicators. In addition, in the process of conveying high-temperature clinker, excessive temperature will also have an adverse effect on related equipment.

[0003] At present, the commonly used cooling equipment is mainly divided into horizontal and vertical. For horizontal coolers, most of them are heavy in weight and high in power consumption, and the cooling space in the horizontal cavity structure is small, and the cooling effect is poor; for vertical coolers , there are often inappropriate feeding methods or ventilation methods. For example, for a certain swing-type flap discharge vertical cooler, the material needs to be discharged by the swing-type flap discharge device after cooling and dehumidification, which is different from this Compared with the reciprocating grid discharge device represented by the invention, the distribution of the blanking material and the flow of the cooling air are not uniform enough

Therefore, the material inside the cooler will agglomerate due to the uneven cooling and heat caused by the sudden cooling, which often leads to the occurrence of material blocking.

At the same time, the relatively complex structure often means that there is a high probability of failure during operation, which affects the operation of production

And most of the equipment also requires higher power due to complex structure, which in turn produces higher energy consumption
